It's simple, when DB was around he operated a bucket brigade that could always summon forth some kind of PR to right the good ship of state CALL. But now he's gone and watcha gonna do?
Remember in Nov a week before expiration CALL suddenly without reason began to plunge? DB was out there the next day with a PR extolling the wonderful earnings. The stock jumped right back up. Then the following week they ran it down mercilessly again into expiration and jammed those shorted puts right up CALL's #$%$ Of course having tricked DB into using up all his PR ammo the week before there was no way he could do a second one in time to revive the stock.
That was either an inside or outside bear raid and boy did it work.
